Animals will only get shocked when the electric fencing circuit is completed. Proper grounding is essential to ensure animals feel the greatest shock and are effectively contained or excluded.
To properly ground your fence charger, one terminal should be connected to the fence, while the other connects to an earth ground wire. Zareba offers several types of ground rods, grounding accessories, and ready-made grounding kits to help you get started.
Consult your fence charger's owner manuals for detailed instructions on how to properly install and ground your specific fence charger.
Zareba ground rods come in both copper and galvanized options. Ground rods should be connected via a ground wire to the ground terminal on the charger to complete the circuit. Ground wires are also made of copper or galvanized metal and may or may not be insulated.
To make installation easier, pour water into the holes you will be pounding your ground rods into.
Electric fencing on sandy, dry, and rocky soils is more challenging to maintain adequate voltage. As a result, you may need to use of a "one-wire" or "two-wire" ground-wire return system and multiple grounding rods.
One Wire Ground System
Two Wire Ground System
Longer fence lines may also require multiple grounding rods. Rods should be spaced 10 feet apart and 50 feet from the grounding system. Use an insulated wire to connect each rod.
Gate Installation Tips
Place gate openings in places where people, animals, and equipment can easily access important buildings and adjoining pastures. Gates should be near corners and never in the middle of a straight fence.
There should be one gate handle for every strand of electrified wire. A variety of gate handles are available from our brands Zareba and Fi-Shock.
For quick and easy assembly use Zareba's gate-handle kits specific to the post and wire types you are using.
Expandable gate handles should always be used with spring gates.
In some cases, an insulated jumper wire may be necessary to carry electrical current to the gate wire.
If installing a permanent gate or spring gate, a 20,000-volt underground hookup wire is needed to carry electrical current to the other side of the gate opening. Insulated wire should be used and run through tubing (e.g. PVC) to protect the wire from cutting on rocks.
Fence testers, also known as voltage testers, voltage meters, or voltmeters, are used to determine the voltage of current running through your fence line.
Voltage testers are useful at troubleshooting grounding issues and electrical shorts in the fence line. Ground problems and shorts can be caused by a variety of issues including broken wires, weeds touching the fence line, or a cracked insulator.
A "fault finding" fence tester with display showing voltage and amp readings, as well as an arrow pointing in the direction of the fault is most reliable way to locate problem spots on your fence line. Zareba's line of fence testers features both simple and more advanced models to help you diagnose problems and keep your electric fence system working properly.
When purchasing a voltage tester, be sure to select one designed for electric fence systems. The fence tester also must be compatible with your fence charger's current type - direct current (DC) or alternating current (AC). Most fence testers will work with both high and low-impedance fence systems.
When using a fence tester, a reading with high amps indicates a short in the fence line. Ideally, your fence line should have a high voltage and very little amps present.
To determine the source of the problem, start by testing the fence charger first. Then work your way systematically around the fence line, starting at the beginning to test voltage in the fence wire. Follow the "fault arrows" on the fence tester display to find the short or grounding issue.
Lightning is a common cause of fence charger failure. The sudden power surge caused by a lightning strike travels through fence wire damaging the fence charger.
When storms are near, unplug your fence charger from its power source to prevent power surges.
Lightning diverters and arresters are useful in diverting lightning surges to the earth before it can cause charger damage. Installed at each corner of the fence, a Zareba Lightning Arrestor can help to divert lightning surges to the ground.
Place a lightning choke between fence line and fence charger to disperse any power surges from lightning strikes. Zareba's Lightning Constrictor acts as a combination lightning choke and diverter to protect from fence-line induced surges.
Zareba AC surge suppressors should be used to protect against AC power surges.
